This style of valve is used for both on-off applications and as throttling control valves. Their design uses an "interference fit", meaning the metal disk is forced in contact with the soft rubber seat to provide a leak-tight seal. Because of this physical interaction, it is normal to replace the seats after a reasonable time in service.
